HTH 67068 Swimming Pool Care Metal & Stain Defense - Prevents Staining and Corrosion Clear

The walls of my vinyl liner were very much a rust color. The floor less so. I poured the whole bottle into my 16,000 gallon pool. I didn't see a difference in 24 hours. I put the solar cover on the pool for almost a week, took it off, and wow, the liner looks like new. I'm guess it works via chelation? Regardless, I recommend it.Something else I do is attach a "whole house" filter onto the end of my garden hose. In it is a 10" 1 micron water filter. This removes the iron from our well water before it goes into the pool. You will need one adapter for the hose threads to fit the filter housing threads but that's it. I guess you could get another adapter and a 2' length of pvc for the outlet side of the filter housing but that just depends on if your situation. Good luck! But...this stuff is great.

Removed metals from water, looking great. We have some so called "Stainless Steel" screws that are rusting, yeah. They don't make stuff like the use to.Anyway, will probably need to use again once more this season as the stains will come back.

This is a staple in my weekly pool.cleaning and maintenance regimen. It does it's job and my pool looks great.

Bought this as same product as more expensive version from pool supply store. One word of caution as this should be treated the same as muriatic acid and is extremely caustic - use goggles and gloves as will cause severe skin burns if in skin contact even briefly.

Easy to use. Value for the money.

This product worked very well. I had a metal stain on my pool liner. I followed the product directions , the stain disappeared. Very satisfied with the results.

Great stuff and also helps with allege.

Good Product
